Hi guys interesting to get all your views. TO GIVE YOU MY RESULTS I got some ofc cable and some Blackrhodium Tango bi-wire, I tested both for around 4 hours with my budget system, ARCAM CD73 ROTEL RA05 SE AMP and monitor audio br5. RESULTS I found the Blackrhodium Performed best, More Detail better stereo image, better timing and a more dynamic sound over the ofc.... In all areas the results were just a little better than the cheap cable not by a huge margin but all the same a better sound, SO YES the £165 cable did perform better in my eyes worth the extra cash after all to spend £500 on my amp £500 on my CD player and £500 on my speakers, the Extra £165 wa worth the investment, Thanks guys
